What Customers Are Saying
Customers praise the wide variety of bit sizes and well-designed storage case that keeps bits organized and easy to find. Many report the bits perform well, drilling through steel efficiently and offering excellent value for the price. However, a substantial number experience premature bit breakage, describing the metal as brittle and weak, with some bits snapping on first use or failing like "a twig in the wall." Several compare durability unfavorably to older brands. Despite these concerns, most customers find the set worthwhile for casual DIY projects, though durability remains a persistent issue.

lead her bottoms distigrate
Would Not Recommendwhen I purchased these bits I was ecstatic, finally someone put a hex head on the bits so you don't have to remove the clamp. or carry 2 drills or 1 drill 1 driver. but these bits suck the. ''lead base" dried and fell apart. cracked and fell off the drill bit itself. which is the reason I got them.

DO NOT USE
Would Not RecommendBought these bits to drill 4 holes in galvanized tubing and ended going to get Milwaukee bits that took all of two seconds to drill. I will not use these bits for anything but a doorstop
Terrible Case
Would Not RecommendSo far, the drill bits have been okay. One broke, but It was one of the small ones. The really bad part is the case they come in. The little yellow latches that hold the bit holders in place are absolute garbage. They constantly come loose and allow the bit holders to move, which causes the bits to dump out in the case. Also, the black latch on the outside pops off almost every time I open it. I would not recommend this.
Not sharp even out of the box
Would Not RecommendI was very disappointed in these bits. They are not sharp enough to drill through oak or pine. Even the larger bits just throw out smoke. The are not a good investment.
Excellent drill bits that were on sale
Would RecommendExcellent drill bits that were on sale. Perfect for your DIY projects.

The drill bits are great & a lot of projects
Would RecommendVerified Purchaser
Broke 2 bits within seconds
Would Not RecommendAbsolutely useless. Drilling mild steel with little pressure, they didn't bite and 2 of the bits broke that were 1.4 thick, so no excuse. Stay far far far away from these, another terrible product from Kobalt.
Comically bad
Would Not RecommendThese bits are so bad it's actually funny. I seat them in a drill, spin them and think "oh, I didn't seat it correctly." But oh, no. The runout is that bad on every bit. It's almost like they were intentionally bent. add to that the worst designed case ever and I've dropped this mess in the trash.
Good price
Would RecommendIs strong
